Lens control
Prosilica GT standard and long cameras
Prosilica GT standard and long cameras can be used with C-/CS-Mount auto iris
lenses of DC type, and P-Iris type.
Both DC and P-Iris lens types use the same standard connector, shown left,
located on the side of the camera. Lens type is automatically determined by the
camera on power-up. Connecting the lens after the camera is powered will not
damage the lens, but it will not be recognized by the camera; therefore, the rel-
evant camera control attributes will not function. If this occurs, disconnect and
reconnect the camera power supply.
Note

Video-type auto iris lenses are not supported.
Motorized CCTV lenses are not supported.
***Read lens descriptions carefully before purchasing***
For example, a “motorized iris lens” may be a bipolar single
axis motorized lens, and not a DC auto iris or P-Iris lens
